Fultz was driving toward the basket 20 seconds into the period when he appeared to accidentally head-butt Embiid. The 7-footer immediately went to the floor. He remained on the floor for several minutes before finally being assisted by Philadelphia's trainer. Embiid sat up once before lying back down on the court. Eventually, he was helped off the court.

Fultz was not injured on the play.

Embiid also suffered a concussion and remains in the NBA's concussion program.

The Sixers clearly need their big man if they're going to make a run in the Eastern Conference playoffs. Embiid leads the team with 22.9 points and 11 rebounds in 63 games, helping Philly clinch its first playoff berth since 2012.
